Time published an April 2, 1973 article, The Paper-Plane Caper, [2] about the paper airplane and its Kline–Fogleman airfoil. Also in 1973, CBS 60 Minutes did a 15-minute segment on the KF airfoil.

On September 5, 2024, three paper planes, one of which was equipped with a radiosonde, were launched from Italy using a weather balloon. The launch reached an altitude of 41,889 meters. [14] The telemetry plane landed in the sea after 1 hour and 59 minutes of flight. One of the other two paper planes was found a week later. [15]
Fire extinguishers must be present at any fueling operation. Airport firefighting forces are specially trained and equipped to handle aviation fuel fires and spills. Aviation fuel must be checked daily and before every flight for contaminants such as water or dirt. Avgas is the only remaining lead-containing transportation fuel.

A wide variety of helicopters and fixed-wing aircraft are used for aerial firefighting. In 2003, it was reported that "The U.S. Forest Service and Bureau of Land Management own, lease, or contract for nearly 1,000 aircraft each fire season, with annual expenditures in excess of US$250 million in recent years".
